About this study

Official title: Comparison of Individually Modified Angled Tube and Conventional Angled Tube in Double-lumen Endotracheal Tube Intubation: A Randomized Clinical Trial

The investigators are trying to compare the individually modified-angled tube and the conventional-angled tube in ease of double lumen endotracheal tube insertion and the incidence of related postoperative complications.

Read the detailed description

Inserting a double lumen endotracheal tube is somewhat more difficult than a single lumen tube intubation because of its larger outer diameter and the more rigid feature. Moreover, the airway axes (oral-,pharyngeal-, and laryngotracheal axis) are not always straight under sniffing condition. Therefore, to make easy to insert a double-lumen tube and reduce the tube-related complications, we are trying to compare the individually angle-modified tube and the manufacturer-provided-angled tube.

Being tested
Mallinckrodt endotracheal tube with a modified angle, Mallinckrodt endobronchial tube with a conventional angle

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Mallinckrodt endotracheal tube with a modified angleDevice

    Also called Tube angle modification, ("MallinckrodeTM endotracheal tube", Covidien)

    At sniffing position, the distal tip of a double-lumen tube is located at the patient's cricoid cartilage level and then the tube is bent at the intersection point of oral axis and the pharyngolaryngeal axis with an angle between the two axes.

  • Mallinckrodt endobronchial tube with a conventional angleDevice

    Also called Mallinckrodt endobronchial tube, Covidien, with conventional-angled tube

    Inserting a manufacturer-provided conventional-angled tube

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The time taken to intubate a double-lumen tube

    The time taken to insert the tube begins when the laryngoscope passes the patient's lips and ends when the tube passes the vocal cords

    Measured: within 60 sec

Secondary outcomes (3)
  1. The number of attempts needed for successful intubation

    Measured: Intubation

  2. The time taken for the first attempt of intubation

    Measured: within 60 sec

  3. Postoperative sore throat, hoarseness or dysphagia

    Measured: 30 minutes and 24hours after extubation

Questions about this trial

What is this clinical trial studying?

A study testing Mallinckrodt endotracheal tube with a modified angle and Mallinckrodt endobronchial tube with a conventional angle in people with Intubation, Intratracheal and Thoracic Surgical Procedures, run by Samsung Medical Center at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Feb 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The time taken to intubate a double-lumen tube (time frame: within 60 sec). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02190032, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Feb 2015.
